Announce of previous Bigloo release (2.3a):
------------------------------------------
Release 2.3a is a major release. It contains an additional back-end: a
JVM back-end (a join work with Bernard Serpette). That is, Bigloo can
compile Scheme program to C for efficiency or to JVM for
portability. Using the Bigloo C back-end, Scheme programs can be mixed
with C programs, using the Bigloo JVM back-end, Scheme programs can be
mixed with Java programs. The distribution contains examples of both
connections.




Announce of previous Bigloo release (2.2a):
------------------------------------------

In addition Bigloo2.0c contains some new minor language features (such
as transcript, interpreter error message notifiers, ...).




Announce of previous Bigloo release (2.0b):
------------------------------------------
Release 2.0b is a minor release. It fixes installation bugs of the

                  * An online documentation


                  * A symbolic debugger


                  * A profiler


                  * Support for user Scheme libraries


                  * ...


Screen shots of the environment are available at:

In addition to the environment, some library facilities have been added:


                  * Socket support


                  * Complete re-writing of the regular grammar compiler. The new
                      regular grammars contains additional constructions such as
                      submatching.




Announce of previous Bigloo release (1.9d):
------------------------------------------


Release 1.9c is a minor release. Mostly, it fixes bugs of the release 1.9b
and it provides a support Bigloo libraries.


                  * Unix pipe
                      ---------
                      Following the idea of Stk (by Erick Gallesio), Unix pipes are
                      handled by Bigloo.


                  * Binary files
                      ------------
                      It is now possible to read and write binary files.




Announce of previous Bigloo release (1.9b):
------------------------------------------


Release 1.9b is a minor release. Mostly, it fixes bugs of the release 1.9
and it provides a DSSSL support and Unicode encoding:


                  * Unicode characters and strings
                      ------------------------------
                      Bigloo now supports Unicode characters and strings but it also
                      maintains traditional ISO-LATIN1 characters and strings support.


                  * DSSSL support
                      -------------
                      Bigloo handles DSSSL keywords, DSSSL named constants and
                      it compiles DSSSL keyword functions.


                  * Object introspection facilities
                      -------------------------------
                      The Bigloo1.9 object system has been extended by the addition of
                      some introspections library functions. Classes are now able to
                      deliver access and mutation functions to their instance's fields.




Announce of previous Bigloo release (1.9):
------------------------------------------


Bigloo 1.9 is at a departure point from the Scheme programming
language as defined in the RnRS report. The main goal of Bigloo
is to allow a Scheme based programming style where C(++) is
usually required. Bigloo attempts to make Scheme practical by
offering features usual to traditional programming languages but
unusual to Scheme:


                  * An extended foreign interface
                      -----------------------------
                      C code and Bigloo code can be merged together. Bigloo functions
                      can call C functions and vice-versa, Bigloo code can use C global
                      variables and vice-versa. Bigloo functions and variables can hold
                      C values (C type value). C values can be allocated from Bigloo
                      program and vice-versa, Bigloo data structures can point to C
                      data structures and vice-versa.


                  * An object oriented system
                      -------------------------
                      Bigloo proposes an extension to Scheme by adding simplified
                      Clos-like generic functions. Bigloo uses single inheritance and
                      mono-dispatch.


                  * A batch compiler
                      ----------------
                      Bigloo compiles modules. Bigloo is a batch compiler. It does not
                      relies on a read-eval-print loop.


                  * An explicit type system and compile time type mismatch detections
                      -----------------------------------------------------------------
                      Bigloo programs may contain type annotations. Bigloo programs are
                      encouraged to contain type annotations. Type annotations hold
                      on variables, function parameters and function results. Type
                      annotations help the compiler in the task of static type
                      mismatch detections and they help the compiler to produce more
                      efficient code.


                  * Simple exceptions
                      -----------------
                      Bigloo discourages the use of call/cc. Instead it proposes
dynamic
                      exceptions a la Common Lisp (by the means of three constructions:
                      `try' that catch errors, `bind-exit' that binds an exception and
                      `unwind-protect' that protects a piece of code from exceptions).


                  * Practical IOs by the means of lexing and parsing tools
                      ------------------------------------------------------


For those who already knows Bigloo
----------------------------------


The release 2.3 mostly presents the additional back-end. However, it
also contains some improvements of the already existing features:
      - Improvement of the Object layer compilation:
          i) Generic functions are now compacted (the memory space used by
generic
          functions is smaller). This has a very little impact on performance.
          ii) Class accessors are now handled more efficiently. That is, the
          code generated for class accessors is much smaller.
      - Cleanup over class indexed fields.
      - Mutable recursive class instances can now be instantiated by the
means of
          the CO-INSTANTIATE form.
      - Enhanced introspection support.
      - New hash tables API ( la Java). New hash tables are now i) more
          convenient to use ii) more efficient.
      - Serializer/deserializer can now be customized for procedures and
opaques
          values.


At last, many thanks to all of you that are providing an inestimable help.
